The cyanide complex of silver formed in the silver extraction in Mac-Arthur's Forrest cyanide proces — Coordination Compounds Chemistry Question
Question
The cyanide complex of silver formed in the silver extraction in Mac-Arthur's Forrest cyanide process is :
Answer: A
💡 Solution & Explanation
Step 1: In the MacArthur-Forrest cyanide process, silver ore is dissolved in a cyanide solution (such as NaCN) in the presence of atmospheric oxygen. Step 2: The silver is oxidized and coordinates with cyanide to form a highly stable, soluble linear dicyanoargentate(I) complex anion. Step 3: The formula of this complex is [Ag(CN)2]^-, which corresponds to option (a).
